According to the UN, the world's urban population will increase by about 60 percent by 2050, from 4 million people in 2015 to 6.3 million in 2050. In other words, by 2050, the UN expects that two out of three people in the world will live in an urban area. In contrast, during the early part of the twentieth century the majority of the world's population lived in rural areas. Some countries will remain rural population dominant, particularly in Africa. However, the UN expects that Africa will experience the fastest increase in urbanization, from 40 percent of the total population in 2015 to 56 percent in 2050.
The UN Department of Economics and Social Affairs Population Division has issued biennial estimates and projections of urban and rural populations by country and major urban agglomerations since 1988. The World Urbanization Prospects reports are used widely by international organizations, research centers, and the media. The UN 2015 Revision of World Population Prospects web site provides the main findings of the 2015 Revision, which are consistent with its total population projections, by country, as published in the 2014 Revision.

Millenials have overtaken Babyboomers by nearly 4 million to become the largest generation in the United States.

Japan is the top country by median age of the total population in the world. As of 2015, the median age of Japan's population was 46.35 years. The top 5 countries also include Italy, Germany, Portugal, and Bulgaria. The median age of the population in Japan increased from 28.78 years in 1970 to 46.35 years in 2015 growing at an average annual rate of 5.45 %. The median age of the population is an age that divides the population in two parts of equal size, that is, there are as many persons with ages above the median as there are with ages below the median. It is expressed as years.
Between 1970 and 2015, the median age of the World's total population grew substantially from 21.54 to 29.6 years rising at an increasing annual rate that reached 3.90 % in 2015. By 2100, the median age is expected to further grow to 41.6 years.
